Two groundwater wells of equal length are installed to a depth of 25.0m located 45m apart (horizontally) in an aquifer that has a saturated hydraulic conductivity of 3.0m/day and an effective porosity of 0.35. The depth from the well top to the water table in well A is 19.7m and in well B it is 18.5m. Using the convention that flow from A to B is positive and from B to A is negative, estimate the Darcy flux in (cm/day).
